随着时代的不断进步和发展,大型精尖放射设备得到普遍应用,各种X、β、γ等射线在医疗上起到了举足轻重的作用。与设备相配套的建筑物在实际应用中应满足设备的条件要求。如何防止射线的穿透,使其外界不受射线的污染至关重要。防止射线穿透的建筑本身有多种方法,例如:铅、铁矿石、钡等。但以上建材都有不利的一面,铅重量过重,惰性较大,不易施工,价格昂贵。铁矿石、重金石、钡等建材用量较小,不易得到,施工也较麻烦。而混凝土是最为理想的防射线建材,在防射线的建筑物中得到广泛应用,在现代化工程建设中占有重
With the constant progress and development of the times, large-scale and sophisticated radiological equipment are widely used, and all kinds of X, β, γ and other radiations play a decisive role in medicine. Matching with the equipment in the practical application of the building should meet the conditions of the equipment. How to prevent the penetration of radiation, so that the outside world from radiation pollution is essential. There are many ways to prevent the penetration of radiation, such as lead, iron ore, barium and so on. However, the above building materials have a negative side, lead weight is too heavy, lazy, difficult to construct, expensive. Iron ore, heavy stone, barium and other building materials smaller, difficult to get, construction is more trouble. The concrete is the most ideal anti-radiation building materials, widely used in anti-radiation buildings, in the construction of modern projects occupy a heavy
